Stamping FEA

I'm trying to model stamping of sheetmetal by setting up an assembly of anvil/die/material for something we already do and know (approximately) the forces involved.  I believe that my constraints are correct (force on top of anvil, uniaxial restraints at the edges of the material, etc.) and the materials are properly defined but it still fails to run.  Contact is set up between the material and die/anvil, meshing works fine.  I can't seem to find any tutorial that covers plastic/permanent deformation.  (Ran this in linear static just for fun but the results of stress is ridiculous.)  Thanks in advance.
